What is the equation of the line with a y-intercept of 4 and a point (8,8)?

The equation of the line with a y-intercept of 4 and a point (8,8) is

Step-by-step explanation:

A linear equation can be expressed in the form

y = m * x + b

where x and y are coordinates of a point, m is the slope and b is the y-intercept. Since this equation describes a line in terms of its slope and its y-intercept, this equation is said to be in its slope-intercept form.

Graphically this equation represents a line.

In this case, you know:

Replacing:

8=m*8 +4

Solving:

8-4=m*8

4=m*8

4÷8= m

Then, the equation of the line with a y-intercept of 4 and a point (8,8) is

$3,200 x 7.25% = $3,200 x .0725 = $232 interest monthly

$232 monthly x 12 annual = $2, 784
